Tommyknockers, tommyknockers, knocking at the door.

So I discovered that the injectors I have cost $22 each to clean. That’s $22 x 8. $176.

Sorry.

All you need to clean these bastards is a fluid at 30 psi. And some way to turn them on (12 volts)

So I made this.

The injector gets clamped between a bushing I bored out for the purpose, and a piece of redi-bar.

The top valve opens so I can spray or pour in a measured amount of carb cleaner; the pigtail is connected to a horn switch, and the regulator uses air pressure to get the fluid up to the appropriate pressure. The glass cylinder at the bottom allows me to catch and reuse the cleaning solvent, and also view the spray.

So you put in a measured amount of fluid, push the button, and time how long the fluid takes to go through the injectors. They were a teeny bit dirty at first, but nothing dramatic. And so I cleaned them all and checked their flow times against one another, and am now ready to reinstall.
